   The application will be deployed to customers through the Windows Store.

   If you think about restrictions, limitations, policies and prospects, can I keep database files of updated deployed applications as described above? If not, how can I keep my app data updated again

   some things:?

   1) This will be more clear to do this by adding a database to a version . Local version can be stored as a local state or setting. Remote version can be inquired through web API.

   2) Do you want users to know about this? Could the user compel the database update? Accordingly, the knobs may need to be highlighted in the UI.

   3) If the size of the file is important, then it may have to be downloaded using it.

   This:

   1. When the app is launched, check Remote Edition (async).
   2. If the version is different, schedule background transfers or file plays based on app size when downloading.
